Good to hear. I might order one of these adapters and try out the 6F8G.
Any idea where to buy the adapter for 6F8G? TY TY

could you graciously confirm which 12AU7 tubes specifically you were referring to? I'm new to tube rolling but I know I want more and better bass and dynamics.

Sincerely!
Sorry I can’t remember that was a loooooooong time ago but I can tell you that use 6SN7 instead 12AU7 family tube is a generally a good direction. Change the coupling caps or bypass them with something like jupiter copper foil caps is a cheaper and more effective way to improve your WA22 instead the expensive tube rolling. I remember the values of the two coupling caps are 0.22uf 600vdc, I don’t recall the minimal voltage rating requirement for the amp because I don’t have the amp here with me (300vdc is probably enough) but 600vdc is a very safe bet, some caps with higher voltage rating sound better than lower voltage rating ones. Thanks!

I just got my WA 22 (2nd gen) today, but I’ll be using these to leap frog the stock tubes right off the bat.
Doing the all Soviet line up.

Rectifier— 5AR4 (Sovtek)
Power tubes— 6N13S (Sovtek) NOS
driver Tubes— Tungsol 6SN7 GTB


Wish me luck. ☺️

My Thomson stock tubes (CSF 6080WA) look a little crooked. Lol. Just tube inspections right now. One of my 6080 tubes has a rattling noise like something is loose inside, however I can’t see any visible problems that something is ajar.
Oh well. Just gotta test it out…

Rattling is OK as long as they sound good, also there is nothing you can do about rattling.
